Government Contractors
How do government contractors comply with public sector e-invoicing requirements?
Government contractors supplying goods or services to public bodies must comply with public sector e-invoicing mandates in each jurisdiction. In the EU, this means invoices in the European Standard (EN 16931) transmitted via Peppol or national portals like Chorus Pro (France), Peppol-AU (Australia), and Peppol-SG (Singapore). Compliance is increasingly a prerequisite for contract award in addition to being a contractual obligation.
What must government contractors do to invoice public bodies?
Government contractors must meet specific technical requirements to invoice public bodies:
- Peppol registration: Obtain a Peppol participant ID from a certified access point provider
- Format compliance: Issue invoices in EN 16931 compliant format (UBL 2.1 or CII)
- Procurement references: Include the contract reference, purchase order number, and buyer routing codes
- CIUS compliance: Apply the national Core Invoice Usage Specification (e.g., CIUS-AT for Austria, NL-CIUS for Netherlands)
- Buyer address lookup: Use Peppol SMP/SML to discover buyer's Peppol address before sending
- Portal alternative: Where Peppol is not used, submit via national portal if available
Frequently Asked Questions
- Do government contractors need separate Peppol IDs for each country they supply?
- A business uses the same Peppol participant ID regardless of which countries it supplies in. However, national implementations may use different identifier types. For example, German public bodies are identified using their Leitweg-ID; Netherlands public bodies use KvK numbers or OIN. The contractor's AP needs to be able to address invoices using the correct identifier type for each receiving country.
- What happens if a government contractor sends an invoice in the wrong format?
- Public bodies are permitted to reject invoices that do not meet the required format under Directive 2014/55/EU. A rejected invoice is not valid for payment until corrected and resubmitted. This can delay payment significantly, triggering prompt payment interest obligations on the buyer side if the delay exceeds statutory limits. Contractors should test their e-invoicing capability before contract performance begins.
